2 Minn. teen girls charged with assaulting cop

The teens started hitting and punching a female officer outside a convenience store at 7th and Cypress around 10 p.m. Wednesday. A male officer in the store came to her aid, the station said. After a brief scuffle, they subdued the suspects.

The female undercover officer "identified herself as a police officer, and they didn't care who she was, and began to take swings and punches at her," St. Paul police spokesman Tom Walsh told KMSP. The male officer had a dislocated finger; the female officer injured her knee, the station said.
